ROLLER SIDE BEARING.

Specification of Letters Patent.

Application filed May 8, 1908. Serial 210. 431,661.

To all whom it may concern:

Be it known that I, JOHN F. O Coxxon, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Iniprovenient in Roller Side Bearings, of which the following is a specification.

My invention relates to roller side bearfor railway cars.

IVIV invention consists in the novel coustruction ofparts and devices and in the novel combinations of parts and devices,

herein shown and described.

In the accompanying drawing forming a part of this specification, Figure 1 is a front elevation of a truck bolster and body bolster of a car provided with my invention. Fig. 2 is a central vertical. section through one of the side bearings and F ig. 3 is a plan view partly broken away.

In the drawing, A represents the truck bolster, A the body bolster, B the lower side bearing plate, C the upper side hearing or plate, D an interposed rotatable disk be tween the upper and lower side bearing plates, E E E a plurality of sets or trains of anti-friction rollers interposed between the lower side bearin plate 13 and the rotatable disk D and separating rings between the diiierent sets of rollers E E E Thelowerside bearing plate B is secured by bolts or rivets b to the truck bolster and it is provided with an inner annular hub or rim 6 an outer annular rim b and with an inclined conical annular tread upon which the several sets of rollers it E E travel.

.The upper side bearing or plate 0 is secured to the body bolster by bolts or rivets c.

l The interposed rotatable disk D has a central conical stud or pivot (Z which [its w'thin the annular hub o of the lower side bearing plate 13. The axis of the hub Z9 and of the central stud or pivot (Z is inclined somewhat to thevertical and toward the center of the car, so that the rotatable disk D occupies an inclined position. The rotatable disk is further provided with an annular rim (P which telescopes over the annular rim 6 of the lower side bearing plate B. The rotatable disk D is further provided with an an nular conical tread (Z parallel to the annular conical tread b of the lower side bearing plate B.

The several sets of anti-friction rollers E E E are arranged concentric with each l l l l l l l l l l proper radial arrangement in respect to,

the lower disk D.

. The lower side hearing plate B and rotatable disk D are so combined with the upper side bearing plate C that said upper side bearing plate contacts with the rotatable disk D outside of its axis or pivot stud (Z, as will be readily understood from Fig. l of the drawing. The rotatable disk D is provided'with an upper rounded or curved bearing face (Z for contacting with the up per side bearing plate C. The inclination of the rotatable disk D to the lower side bearing plate B is preferably such that the annular conical treads 6 (Z of said plate B and disk D under the upper side bearing 0, will. be substantially horizontal, as will be readily understood from Fig. 2 of the draw- 111g.

1. In a roller side bearing, the combination with body and truck bolsters, of an upper side bearing plate secured to the body bolster, and a lower side bearing plate secured to the truck bolster, an interposed inclined mtatable disk and a plurality of sets of radially arranged anti-friction short cylindrical. peripherally-contacting rollers interposed l'ietwcen the lower side bearingplate and said rotatable disk, srl lower bearing plate and sad rotatable d'k having annular conical tree. para l v.uh other the outerset beingcoinpos or a greater number of rollers than the inner set sul'istanz. specified.

a roller side bearing, the combinath body and truck bolsters, of an up per side bearing plate secured to the body holster. and a lower side bearing; plate sooured to the truck bolster, an interposed ine bearing plate B and rota-table cl ined rotatable disk and a pluralityof sets Iatented Nov. 16, Midi).

the outer being composed of a greater numb r of rollers than the inner set substantially specified.

ln a roller side bearing, the combination w h body and truck bolsters, of an up-' a bearing plate secured to the body bolster, and a lo *er side bearing plate se curcd to the truck bolster, an interposed inclined rotatable disk and a plurality of sets radially arrau ed anti-friction short cy- T icale 'phe ally-contacting rollers in- "osed between the lower side bearing ate and said rotatable disk, said lower bearing plate ano said rotatable disk having annular conical treads parallel to each other, and a separating ring between adjacent sets of anti-friction rollers, the outer set being composed of a greater number of rollers than the inner set substantially as specified.

4, In a roller side bearing, the combination with body and truck bolsters, of an upper side bearing plate secured to the body bolster, and a lower side bearing plate secured to the truck bolster, an interposed inclined rotatable disk and a plurality of sets of radially arranged :mti-:triction short cy lindrical peripherally-contacting rollers interposed between the lower side bearing plate and said rotatable disk, said lower bearing plate and said rotatable disk having annular conical treads pa 'allel to each other,

and a plurality of separating rings interposed between adjacent sets of anti-friction rollers, the outer set being composed of a greater number of rollers than the inner set substantially as specified.

5. In a roller side bearing, the combination with body and truck bolsters, of an upper side bearing plate secured to the body bolster, and a lower side bearing plate secured to the truck bolster, an interposed inclined rotatable disk and a plurality of sets of radially arranged antii'riction short cylindrical periplierally-contacting rollers'interposed between the lower side bearing plate and said rotatable disk, said lower bearing plate and said rotatable disk having annular conical treads parallel to each other, said lower bearing plate having an annular inner rim or hub and an annular outer rim, the outer sot being composed of a greater number of rollers than the inner set substantially as specified.

6. In a roller side bearing, the combina tion with body and truck bolsters, of an upper side i caring plate secured to the body bolster and a lower side bearing plate secured to the truck bolster, an interposed inclined rotatable disk and a plurality of sets of radially arrar ed anti-friction short cylindrical per-2 herally-contacting rollers 1nterposed between the lower side bearing plate and said rotatable disl, said lower bearing p ate and said rotatable disk having annular conical treads parallel to each other,

and a plurality of separating rings inter posed between adjacent sets of anti-friction rollers, said lower bearing plate having an annular inner r m or hub and an annular outer rim, and saidrotatable disk having an annular rim, the outer set being composed of a greater number of rollers than the inner set substantially specified.

and said rotatable disk, said lower bearing plate and said rotatable disk having annular conical treads parallel to each other, and a plurality of separatin" rings interposed between adjacent sets c anti-friction rollers, said lower bearing plate having an annular rim or hub and an annular outer rim, and said rotatable disk having an annular rim and a central pivot stud journaled. upon said lower side bearing plate, the outer set being composed of a greater number of rollers than the inner set, substantially as specilied.
